Given numbers are 422, 418, 611, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(422, 418) = 88198
GCD(422, 418) = ( 422 x 418 ) / 88198
= 422 / 418
= 422
Step2:
LCM(2, 611) = 1222
GCD(2, 611) = ( 2 x 611 ) / 1222
= 2 / 611
= 2
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 422, 418, 611, 278 is 1
